reverb pedals for bass Reverb

reverb pedals for bass ReverbREVERB is an all analog circuit implementing four separate PT2399 delay lines, each spaced roughly 1. 5x apart in time, insuring minimal overlap. This design targets a generic, natural resonant echo chamber effect, crudely similar to a 4 spring topology. Tonality is clean with minimal distortion, very low noise, and none of that metallic after taste. Specifications True bypass Swell (decay) control 0dB gain 82k ohm input impedance 0. 05% distortion @

Testimonials

• "I recently bought one of your reverb pedals and wanted to tell you how incredible it is. I’ve been chasing a classic 'echo chamber' reverb sound for ever and finally - FINALLY - I’ve found it in your pedal. Thank you! A related note - this is the only reverb pedal I’ve used that sounds better running into the front of the amp rather than the fx loop. How did you manage that magic?"
• "I did get it (your Reverb pedal) set up and played it for a couple of hours now - I love it! As you already know full well but I had to discover by listening, your Reverb is an entirely different type of sound compared to DSP reverb pedals. I'm using it with a Grace FELiX 2 + a Louis Electric RB12, and it is clear to me that your pedal is extremely, as in totally, clean sounding. Its effect is sufficiently subtle, even at maximum Swell that I had to convince myself I had set everything up correctly!"
• "I have received the reverb, and tested it briefly at bedroom levels. It sure is a pedal with its own personality. NOT a conventional reverb, but I suspect it may be perfect for THE sound I'm chasing for in one of my band."

Analog* Discussion

Some folk believe the PT2399 delay chip should be classified as digital. I say no! There are no digital words representing the signal, nor any such arithmetic or computing done. The input signal passes through an analog opamp for filtering, which then drives a low pass filter and comparator input. The analog comparator makes a decision to go higher or lower, and this is the information passed into the 1-bit digital memory. As I said, it is not a digital representation of a signal, but merely a decision to go higher or lower, and even then the amount of high or low depends on analog supplies, so they need to be clean. The amount of signal in each bucket is dependent on power supply voltage, so it's not truly a one or a zero. The reverse process occurs at the output of the memory, where an analog charge is pumped into or pulled out of a capacitor for each clock cycle, depending on the decision bit. This is then fed into another analog opamp configured as a low pass filter, thus removing high frequencies and sampling artifacts. That's it, a very analog process. No algorithms, no software.
